Plain English Summary

1/10 complexity

This instrument cancels a specific aircraft safety directive effective 7 September 2015.

What it does:

Repeals Airworthiness Directive AD/PT6A/28 Amdt 1 (which applied to Pratt & Whitney PT6A aircraft engines—commonly used in turboprop planes)
Removes the legal requirement for aircraft operators and maintenance providers to comply with the specific safety instructions, inspections, or modifications contained in that directive

Who it affects:

Owners and operators of aircraft fitted with Pratt & Whitney PT6A engines
Licensed aircraft maintenance engineers and approved maintenance organisations responsible for these engine types

Why it matters: Airworthiness Directives are mandatory compliance orders issued when safety issues are identified in aircraft or components. Removing this directive eliminates the associated regulatory burden for affected operators, typically because the safety issue has been resolved through other means, the directive has been superseded by a newer requirement, or the original safety concern no longer exists.
